I've been searching through all of the various sources for xPages development and haven't found the answer yet.  Either that or I completely missed it.  (Which is very likely.)

Does anyone know how I can validate that a Radio Button Group control has a radio button selected before the xPage is submitted?

Mike,
I'm not sure I've tried to validate a Radio Button in XPages yet but I did write a blog post about this once that might help.

You can set the "required" property to true, then you can add an error message control to display the required message to the user.

I use this technique in my survey sample app on my website. If you download it, look at the TakeSurvey xpage.

How do you want to validate your radio button group? There are a variety of options, as I'm starting to blog about ({ Link } I spent over a week trying various things because I had very configurable requirements, and I'm sure I can help you.
The blog also has a link so you can see what I've done to validate radio button groups, using dojo tooltips.
Client-side is one option, but there are server-side options. The solution I use is server-side.

Sorry, the link included the closing bracket: { Link }
I tried the xp:validateRequired validator, but couldn't get it to display the message I wanted to use.
By all means email me - pwithers@intec.co.uk

@1: Hi David, I saw your technique, but it won't work for me because my radio button options are dynamic. I use an @DBLookup to retrieve them from a keywords view.

@2: John, I tried that but the validation was never thrown. Let me try that again. I may have done it wrong.

@3: Paul, I saw your post but your solution looked a bit complex for what I need. My xPages skillset is in its infancy at the moment, so I'm trying to accomplish this the simplest way possible.

All I need to do is verify that the user selected an option in the Radio Button group.
